ABSTRACT:
An inflator (10) includes a striker (20) movable into engagement with a burst disk (16) to rupture the burst disk and allow stored gas to flow from a container (14) through passage means (60-64) into an air bag (not shown). A piston (30) connected for movement with the striker (20) is disposed in a cylinder (80). An initiator (32), upon actuation, moves the piston (30) in the cylinder (80) to move the striker (20) into engagement with the burst disk (16). An end portion (154) of the striker (20) removes a portion (142) of the burst disk (16) which includes an area of intersection of score lines (132-138) on the burst disk. Combustion products of the initiator (32) flow into the cylinder (80). The combustion products flow through openings (180, 152) around the piston (30) and around the striker (20) into the passage means (60-64) prior to and after rupturing of the burst disk (16).
